Hello,

        Just out of curiousity what arch, and, if
  possible, what os does your code run on?
        I develop on x86 with debian with grsecurity
  patches. My production machines are the same. Due to
  money restrictions, I have to do with what I have :)

        So what do you develop on and what production
  systems does your code run on? What archs are in
  airplanes, I don't know anything about it. Hopefully
  it isn't Windows :D
        Figured for the way Ada is, designed not to fail,
  I would assume that x86 would not be used much by the
  DoD and airlines, etc.
        Are tandems used?
        Just curious :)

Thanks,
Chris
